Here's a drawing for mix I made last year called "Underwater Music". Probably influenced by too much Cousteau documentary watching, it's a collection of tracks that I feel evoke an aquatic or nautical vibe akin to being underwater yourself (not just referencing water and such in the titles). Of course, a few of these songs were pulled from records that very blatantly have those themes (such as Pram's "Sargasso Sea" and the YLT soundtrack). For the most part, though, I just felt like they fit. I never have much luck posting public links to things like these because they tend to get zapped, but send a note if you would like a link to it.
